A purple tongue can be caused by various factors, including poor circulation, certain medical conditions like cyanosis, or vitamin deficiencies, particularly in vitamins B12 and C. It may also result from dehydration or the presence of specific infections. Additionally, certain foods, medications, or smoking can temporarily stain the tongue purple. If the discoloration persists, it's advisable to consult a healthcare professional for a proper diagnosis.
